Does anyone have any idea what food would be best to feed hens to extend their life? I don't care as much about getting eggs as I do for them simply being pets. I of course want them to be healthy, however I learned about Matilda the chicken that lived to be 16 years old, and based on all the health issues mine have had in the past from feeding layer crumbles, and how 3 of my 4 no longer lay, I wonder what it was that that chicken Matilda ate to live so long or anyone elses chickens that have lived over 10 to 15 years. I started out with 11 hens, 1 rooster, and now am down to 4 hens and 1 rooster. 2 of my hens died unexpectedly at young ages of 2 and 3, another died from unknown respiratory issues that all occurred within 3 days, another died from a prolapsed vent, 1 died from sour crop (choking on her food) when I wasn't home. 1 died from reproductive cancer. 1 died from egg yolk peritonitis, and currently I have one who is not doing well with reproductive cancer that has spread to her stomach, causing sour crop. Any advice would be great. In the past I had 2 from my first flock years ago that lived to be 5 and 6. 1 was killed by fly strike and it was too late to do anything, when I discovered, and the other one was killed by a racoon at 6 (up until she died, she laid every day and had no health issues). My current flock contains a 6 year old (almost 7) who has cancer, 2 almost 6 year old's (one who lays, another who doesn't), and 2 who are five (one a rooster, the other a non-laying hen).
